" Open the zip (my mod) file. 
 Copy (or hold & drag) "Liveries" folder (from my mod) into "C:\Users\{your-user-name}\Saved Games\DCS" folder and overwrite. "     
overwrite what , I have not liveries folder ???     
I d' ont forget to make that  :     
" Run DCS World. 
 Go to OPTIONS > SPECIAL Tab > KA-50 row. 
 Select "Ricardo HD" from Customized Cockpit pull-down menu. 
 Click "OK". "
